Abstract: PURPOSE:To prevent inversion of pictures by incorporating carbon blacks having 10mmu-30mmu and >=30mmu average particle sizes, by 0.5-10 pts.wt. and 0.1-1.0 pts.wt., respectively, into the outermost magnetic layer. CONSTITUTION:The magnetic recording medium of this invention has plural numbers of magnetic layers. The outermost magnetic layer contains carbon blacks having 10mmu to <30mmu and >=30mmu average particle sizes, by 0.5-10 pts.wt. and 0.1-1.0 pts.wt., respectively, to 100 pts.wt. of the magnetic powder in the outermost magnetic layer. It is preferable to add carbon black of >=30mmu average particle size by 0.1-20 pts.wt. to 100 pts.wt. of the magnetic powder in a lower layer (inner layer) of the plural magnetic layers. Thereby, the surface of the inner layer is roughened, by which the surface of the outermost layer is finely roughened.

Filed: 1986-02-06
Abstract: PURPOSE:To remove contaminants contained in a heat-resisting resin for improving the characteristic of an insulation layer, by utilizing the fact that the presence of the contaminants in the heat-resisting resin partially inhibits formation of a spin-on glass layer. CONSTITUTION:A prepolymer of polyimide is applied over a wafer 1 and heated to form a heat-resisting resin layer consisting of a polyimide layer 2. The polyimide layer 2 thus formed contains contaminants 3 such as dust or the like which are produced in any part after a filter of the applying apparatus. Spin-on glass then applied over there and heated to form a silicon oxide film 4. However, the silicon oxide film 4 is not formed on and around the contaminants 3 because of radical difference in height due to the presence of the contaminants. The polyimide layer 2 is then etched with an etching gas principally consisting of oxygen gas. The contaminants 3. are removed by the etching of the polyimide layer 2. Subsequently, another polyimide layer 5 is applied on the polyimide layer 2 and heated so that the spaces which have been occupied by the contaminants are filled with the polyimide layer 5 while other parts are covered with multiple layers of polyimide.

Title: Fuel cell system
Inventor: NONOBE YASUHIRO
IPC: H01M8/04
Filed: 1995-01-18
Abstract: PURPOSE: To miniaturize a fuel cell system and to enhance its operating efficiency. CONSTITUTION: At system startup, a first valve 50 is fully opened, a second valve 54 is fully closed, and only hot water that was made to exchange heat with a methanol reformer 20 by a heat exchanger 48 is forced to flow into a solid-polyelectrolyte fuel cell 12 to quickly raise the cell temperature. If the improper wetting (excess or insufficient moisture) of a solid polyelectrolyte film is recognized from the water percentage WPEFC of the fuel cell and the resistance RPEF of the polyelectrolyte film, the apertures of both valves are adjusted according to the water percentage WPEFC of the cell and the resistance RPEFC of the polyelectrolyte film so as to adjust the temperature of cooling water flowing into the PEFC 12 to low or high temperature. Therefore, the PEFC 12 is cooled or warmed as the low- or high-temperature cooling water flows into it.

Title: Electrophotographic device
Inventor: ASAI SHINJI
IPC: G03G15/06
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To provide an electrophotographic device without sticking a carrier to the surface of a photoreceptor, without disturbing a potential latent image and without causing any fog phenomenon by providing a current limiting circuit between a developing roller and a power source for applying a bias voltage to the developing roller. SOLUTION: A developing machine 4 is filled with a developer 422 of a mixture of toner and carrier, the developer 422 is magnetically attracted to the developing roller 401 and it is rotated. As an example of the current limiting circuit, a diode 402 is connected not to make a current flow from the developing roller 401 to the power source 403 and further, a bias voltage VB is applied by the power source 403. The voltage of a residual charge when the toner on the developing roller 401 is not used for development on the photoreceptor 1 is higher than the bias voltage VB, so that the current tries to flow into the power source 403. However the current flowing through the power source 403 is limited by the diode 402. Thus, negatively charged carriers are never stuck onto the photoreceptor 1.

Title: Control device for uniform linear velocity of disc-shaped information recording material
Inventor: FUJIMAGARI YUKIO
IPC: G11B19/28
Filed: 1981-02-20
Abstract: PURPOSE: To control the uniform velocity of an equal density recording disc easily, by controlling a motor for rotating a disc finely by a reference linear velocity after controlling it roughly on a basis of a reference velocity.  
     CONSTITUTION: A slit 12' of a slit disc 12 is detected by a photo sensor 23 which moves through a radial motor 17, a cross roller gauge 20, etc. in accordance with the movement of a pickup 15 in the direction of the radius. A detection pulse, which corresponds to the rotation velocity of the motor 17 for turning a disc 2, from this sensor 23 is compared with a pulse corresponding to a reference velocity from a monostable multivibrator 32 to become a rotation velocity control signal, and this signal is applied through a multiplexer 35 to control roughly the rotation of a motor 1. Meanwhile, when a frequency signal corresponding to the linear velocity of the disc detected by the pickup 15 has phase locked in a PLL circuit 27, a linear velocity control signal passing through a phase comparator 29 is selected by the multiplexer 35 to control finely the rotation of the motor 1, and thus, the rotation of an equal density recording disc is controlled to a uniform velocity without a potentiometer which outputs a pickup position signal.

IPC: B44C1/16
Filed: 1990-02-05
Abstract: PURPOSE:To judge whether received transmission density is within a transmission density range established according to an appropriate ink quantity or not by a method wherein the transmission density is measured by receiving laser light having transmitted a light diffused transparent ink part of a transfer foil with a photomultiplier after emitting the laser light from one side of the transfer foil. CONSTITUTION:A transfer foil 1 on a base sheet 2 of which a light diffused transparent ink part 3 of a specific pattern is printed passes between a light source 10 and a photomultiplier 11 in a printing press 5. A specific laser light is emitted from the light source 10 toward the photomultiplier 11. Then, this laser light passes an irradiated position of the light diffused transparent part 3. By receiving the laser light having transmitted the light diffused transparent ink part 3 with the photomultiplier 11, transmission density is measured. In the case where a microcomputer 15 judges that the measured transmission density is not within an established transmission density range, processes such as that it is make known to an operator with a warning lamp, a warning buzzer, etc., that the printing press is stopped, or that a mark or the like are attached to a defect position of the transfer foil are performed.
